Try edxporting from avid at different settings. When you do an export change the audio settings there-- before you export.

If you can ingest the footage and it plays in 'signle camera mode' you should be fine with mukticam mode.

If they don't have QuickTime you will probably have to transcode the video to a different container (from .move to whatever they can play). You won't be able to just transcode the audio only though. You also don't have to re-export the file from avid-- just convert it in a conversion program.

Have you tried selecting your audio tracks, then schoosing special from the drop down menu then selecting audio mixdown, or are you doing your mixdown a different way? What frame rate are you working in?

Have you installed the PDW-U1 Sony software? Have you been able to export before? Or is this the first time you have tried?

Try doing a CTRL+9 then clicking the format tab.

What frame rate)s) are you working in? Is the audio out, too? If it was out by 2 frames it would make more sense.

Yeah, that is too bad. It would be a nice feature request as a lot of people use different audio sources.

What about grouping the clips?
